Abstract:

We analyze the production of triple pseudoscalar Higgs bosons in the decay channel of

Z\rightarrow AAA

for light pseudoscalar bosons when the corresponding scalar boson is too heavy to be produced by

Z

decay. Analytic results are obtained both at the tree level and at the one--loop level. The branching fraction can be as large as

10~{-5}

which should be detectable at LEP.
